Now I try to create a Rails project in Rubymine 4 but there's an error: "Rails version - no Rails gem found". Though it’s new, I recommend it because it’s all-in-one and fast.I installed Rails 3.2.3 and Ruby 1.9.3 going through this solution.
#RUBYMINE RVM INSTALL#
There are no shims (unlike Asdf or Rbenv) and it doesn’t override the cd command (unlike RVM). First of all, due to the Ruby environment that comes with Mac, if you want to install the package, you need to name it with sudo. ruby-version file in a project directory and, if there’s no version specified for a project, it will default to a global Ruby version. Like the other version managers, it checks for a. The installer is fast, and Frum requires no dependencies (it’s an all-in-one Rust executable you can install with Homebrew).Īfter you install Frum, you must modify your ~/.zshrc file so Frum runs in your local shell environment. Unlike Asdf, Chruby, or Rbenv, it includes a built-in Ruby installer command so there’s no extra program needed to install Ruby. Frumįrum is written in Rust, a good language for fast command-line execution of system software. Chruby is a great choice, but you may want to try Frum, the newest Ruby version manager.
I used Chruby for several years and had no problems with it. It works fine for troubleshooting with which. That’s all that’s needed for Chruby to switch among Ruby versions. There’s no need to modify your $PATH, as Chruby does that for you, based on the Ruby version you’ve selected.Ĭhruby also sets certain environment variables for Ruby. You’ll need to modify your ~/.zshrc file so Chruby runs in your local shell environment. Unlike Rbenv or Asdf, it doesn’t intercept commands using shims.
Unlike RVM, it doesn’t override the cd command. ChrubyĬhruby is not as well-known as RVM or Rbenv, but it’s championed by several prominent Ruby developers. (Rbenv intervenes every time you run a Ruby command unlike RVM, which intervenes only when you change directories.) For developers who notice the delay, or don’t like the idea of shims, there is Chruby or Frum. Second, a shim can add microseconds of delay to execution of a Ruby command. For example, the which ruby command shows the Rbenv shim, not the actual Ruby version (you must set the RBENV_DEBUG environment variable if you want to see the actual Ruby command). First, shims make troubleshooting more difficult by hiding the actual command. The shim calls the rbenv exec command, which determines which version of Ruby to use before running any Ruby command. (Asdf also uses shims.)Īfter installing Rbenv with Homebrew, you must modify your ~/.zshrc file so the Rbenv shims take precedence over ordinary Ruby commands. Rbenv uses shims to intercept common Ruby commands. RbenvĪlong with RVM, Rbenv has long been the most popular version manager for Ruby. The additional complexity isn’t needed, so many developers have switched to a newer version manager such as Rbenv, Chruby, or Frum. I am getting following error while remote debugging through RubyMine IDE. Gemsets are no longer needed, since Bundler was added to the core Ruby to manage gem dependencies. However, RVM includes additional features such as gemsets.
RVM properly displays environment variables to reveal the Ruby and gem version and location, which can help diagnose problems. To override the cd command, the RVM installation script changes the shell configuration file (the ~/.zshrc file on newer Macs). RVM modifies the system cd command to set environment variables when you change directories. RVM was the first popular version manager for Ruby. Differences among the four lie in speed, complexity, and how each switches Ruby versions. If you only intend to develop applications using Ruby, choose among the four Ruby-only version managers: Chruby, Frum, Rbenv, and RVM.
